Could not get firmware version.

[Radeon24]

Hello,
I have an issue with my HDHR5-4DT wich has the latest firmware 20200225 :

 File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 179, in _async_setup_platform
   await asyncio.wait_for(asyncio.shield(task), SLOW_SETUP_MAX_WAIT)
 File "/usr/local/lib/python3.7/asyncio/tasks.py", line 442, in wait_for
   return fut.result()
 File "/config/custom_components/hdhomerun/sensor.py", line 47, in async_setup_entry
   'sw_version': adapter.get_version(),
 File "/usr/local/lib/python3.7/site-packages/hdhr/adapter.py", line 335, in get_version
   raise error_for_result(result, message)
ConnectionError: Could not get firmware version (-1).

I am using the master branch via HACS on HassIO.

Thank you.

Thanks for the report. A status of -1 from the libhdhomerun library indicates a general "connection failure" so unfortunately there's not of lot of info to go on. If you have the hdhomerun_config command-line utility wherever HA is running I would check whether you are able to connect that way - and if not, that would seem to point to an issue at the network level, maybe a firewall or something.

It would be possible to make some changes and keep going with an empty firmware version if the API call fails, but I have a feeling that the same connection errors will come up again later when querying the actual tuner status.

I've just install hdhomerun_config on my HA host and all seems to be fine :

alfred@alfred:~/hdhomerun/libhdhomerun$ ./hdhomerun_config 10.42.20.216 get /lineup/scan
state=complete progress=100% found=40
alfred@alfred:~/hdhomerun/libhdhomerun$ ./hdhomerun_config 10.42.20.216 get /sys/hwmodel
HDHR5-4DT
alfred@alfred:~/hdhomerun/libhdhomerun$ ./hdhomerun_config 10.42.20.216 get /sys/model
hdhomerun5_dvbt
alfred@alfred:~/hdhomerun/libhdhomerun$ ./hdhomerun_config 10.42.20.216 get /sys/version
20200225

From the HassIO container it's okay too 👍

config $ hdhomerun_config 10.42.20.216 get /sys/version
20200225
config $ ifconfig

And this is my configuration in Home Assistant :

hdhomerun:
  sensor:
    - host: 10.42.20.216

So, I don't understand why there is this error...

Well that is puzzling. 🤔 I'll take a look at the libhdhomerun source to look for some other ideas, otherwise I guess we can make the firmware version optional and see what happens.

I'm not very good with ctypes and couldn't really understand the hdhr library, but I've narrowed down why this is happening (maybe?) - not sure if this helps or not:

---

ha-hdhomerun/custom_components/hdhomerun/sensor.py

Line 25 in c906190

devices.extend(HdhrUtility.discover_find_devices_custom(ip=ip))

that gives a list of <hdhr.types.TYPE_hdhomerun_discover_device_t> objects which is used to create the adapter:

ha-hdhomerun/custom_components/hdhomerun/sensor.py

Lines 34 to 38 in c906190

	device_id = device.nice_device_id
	tuner_count = device.tuner_count
	_LOGGER.debug("Detected %d tuners for device: %s" % (tuner_count, device_id))
	adapter = HdhrDeviceQuery(HdhrUtility.device_create_from_str(device_id))

the error described in this issue is encountered with that adapter. But things seem to work fine if I create the adapter from the IP address directly, using nice_ip instead of nice_device_id:

>>> device = HdhrUtility.discover_find_devices_custom(ip='192.168.1.100')
>>> ip_adapter = HdhrDeviceQuery(HdhrUtility.device_create_from_str(device.nice_ip))  # instead of device.nice_device_id
>>> ip_adapter.get_version()
'20200907'
>>> ip_adapter.get_model_str()
'hdhomerun4_atsc'
>>> ip_adapter.get_tuner_streaminfo()
[]
>>> ip_adapter.get_tuner_program()
'0'
>>> status, raw_data = ip_adapter.get_tuner_status()
(<hdhr.types.TYPE_hdhomerun_tuner_status_t object at 0x801a16bc0>, b'ch=none lock=none ss=0 snq=0 seq=0 bps=0 pps=0')
>>> status.nice_channel
'none'

to confirm, using the nice_device_id instead:

>>> id_adapter = HdhrDeviceQuery(HdhrUtility.device_create_from_str(device.nice_device_id))
>>> id_adapter.get_version()
Could not get firmware version (-1).
